Practical exercise applying the concepts from my course on SOLID principles and hexagonal architecture for Master's students in CTO and Tech Lead roles at HETIC.
This is a simple PHP application that allows you to create orders, add items to the order, calculate the total by applying VAT, and view orders.
With this deliberately poorly designed code, where persistence and the command system are tightly coupled, the initial objective is to encourage students to write unit tests without modifying the source code, in order to demonstrate how challenging it is to test an application when components are strongly interconnected. In a second phase, the goal is to ask them to migrate the persistence to a non-relational database without altering the existing code, thus illustrating the complexity of evolving a poorly-architected application. Finally, in a third phase, the aim is to instruct students to refactor the code following the SOLID principles and the taught hexagonal architecture, making the code more understandable, testable, and adaptable.
